HDPE 4 Cavity Blank Mold - Solid Black

$ 45.00

High-density polyethylene (HDPE) is a polyethylene thermoplastic, used in the production of plastic bottles and cutting boards. HDPE is considered more durable and safer than PVC. We use HDPE to make an alternative to our blue silicone molds, and it is available in most standard single blank or block sizes, as well in custom order dimensions.

This mold is solid black HDPE and does not contain any screws. 

Cast Dimensions: 7/8" x 7/8" x 5-1/4" each cavity (casts up to 4 blanks)

Mold release sprays help to extend the shelf life of our molds. We recommend Stoner Thermoset for Polyester and Epoxy Resins, and Stoner Urethane for Urethane Resin.
